Using Datalogger in the
Teaching of Physics
charge/discharge - Experiment with different component values.
Fridges and Freezers - Plot temperature inside a fridge or freezer.
Also plot temperature of the heat exchanger on the back. How is
temperature affected by opening the door or by adding something
hot to the fridge. Can you see the effect of the thermostat?
Fruit Power - Make a fruit battery. Experiment with different
fruits and electrodes.
Global Warming - Show how CO2 can effect warming. Heat two bottles
using a lamp. One contains air and the other CO2.
Heat Insulation - Wrap test tubes in different insulating materials.
Compare wet and dry insulation
Heat Loss Through Windows - Compare temperature inside and outside
a window over 24 hours. If possible compare single and double
Infra red remote controls - Use a photo diode to view the invisible.
Investigating the effects of wheel imbalance
Light decay (inverse square law) - How does light level decay
with distance from source
Light Insulation - Experiment with different materials to see
which cuts out the most light. Does using two bits of insulation
have twice the effect?
Measuring the speed of sound - Using 2 microphones or musical
Output of a solar cell - What factors affect the output voltage
and power available.
Response time comparison of two types of heat sensor
Sound Decay - Use a sound source with a constant level and plot
how it decays with distance.
Sound Insulation - Use a sound source with a constant level and
experiment with different insulating materials.
Sound waveforms - Use oscilloscope to show the sound waveforms
produced by someone whisting, speaking or singing. Switch on the
spectrum analyser to see the frequency components (e.g. who's
whistle has the highest frequency, who can whistle the loudest?)
Sound waveforms of musical Instruments - Look at the scope waveform
and FFT spectrum of different musical instruments.
